2.7

I am in the process to try this, but having difficulty. I tried to look for documentation that explains this process of updating the 5i25, but can't find anything.

I did the following:

ptd001@ptd001:~/linuxcnc/5i25/utils/linux$ sudo ./mesaflash --program 5i25_7i77x2.bit --device 5i25
ERROR: Board 5I25 doesn't support FPGA resetting.

any advice please. even a link to the correct documentation.


in the Mesa documentation I see W4, and W5 jumpers

PRECONFIG PULLUP ENABLE
The Xilinx FPGA on the 5I25 has the option of having weak pull-ups on all I/O pins
at power-up or reset. The default is to enable the pull-ups. To enable the built-in pull-ups,
(the default condition) jumper W4 should be placed in the UP position. To disable the
internal pull-ups, W4 should be in the DOWN position.
PCI BUS ISOLATION
The 5I25 uses bus switches to provide 5V tolerance on the PCI bus. These bus
switches can be turned off to disconnect the FPGA from the PCI bus. This is valuable
when debugging FPGA PCI firmware. W5 controls the PCI bus isolate function. For
normal operation W5 must be in the UP position. To disconnect the FPGA from the BUS,
move W5 to the DOWN position.

should I move W5 down?

Because of the error:

in order to flash, do I need to move W5 down?

do I need to set any jumpers?

okay. thank you.

I would like clarity on which jumpers needs to be swopped on the 5i25(I believe it must be W4 or W5), and which jumper settings on 7i77 (I believe it is W4 and W12 on 7i77)

will this make any difference?

It's still giving the same error.




I'm not sure what to do from here. seems like 5i25 is updated successfully now, but still requires some other update.

I have another machine exactly the same that I will need to update. I'm getting worried now, because I am trying so many different things, that I don't know what I have done to get where I am now. it would be nice to have some instructions so that this excersize will not be so painfull. I have done 27 machines to date, and would like to do the updates to all machines.
